This study examined whether sex, empathy, or social skill is the better predictor of self-reported support behavior and perceptions. Research has shown that certain personality traits have a differential effect on the amount of support a person receives. Previous research has also show that females report receiving more support and needing more support than do males. Female (N=71) and male (N=54) college freshmen maintained the Rochester Interaction Record for 2 weeks, recording various types of support they received during their interactions. They then completed the Social Skills Inventory and the Empathy Scale. Results confirmed the findings of previous research for sex differences on the personality and support measures. Regression analyses showed that overall, sex was a better predictor of support than personality traits. Interestingly, the regressions also showed that emotional sensitivity was positively related to all the support indices for males, while personality was a poor predictor for female support indices.
